Abstract
A furniture member mechanism includes upper and lower housing structures, the lower housing structure including first and second side frames. A mechanism is disposed within both the upper and lower housing structures, including first and second lever arms having an upper end, a body extending into both the upper and lower housing structures, and a lower end positioned in the lower housing structure and rotatably connected to the first and second side frames. A bracket is connected to the first and second side frames. First and second biasing members are connected to the first and second lever arms and the bracket. The first or second biasing member extends when the first or second lever arm is rotated from an initial position in a lever forward direction. A biasing force of the first or second biasing member biases the first or second lever arm toward the initial position.
